# Rudolf Kaufmann

> Rudolf Kaufmann, son of the physicist Walter Kaufmann, was a palaeontologist and geologist, and is best remembered for his work on allopatric speciation and punctuated equilibrium in the trilobite genus Olenus in the Upper Cambrian of Sweden and on the island of Bornholm. He was a brother-in-law of Curt Teichert, the well-known German-American palaeontologist and geologist. Studying the Upper Cambrian alum shales in Sweden, Kaufmann found that the trilobite genus Olenus occurred in an unbroken sequence of sediments covering a considerable period of geological time. He was thereby in a position to track the phylogenetic evolution of Olenus, that is, the rise and fall of species within the genus and the changes in their morphology. He coined the idea of Artabwandlung, which is the tendency of clade elements in the same environment to show the same morphological trends.
